Puzhao Temple is located in Hancheng,Shaanxi Province.There are five exquisite painted clay sculptures of the Yuan Dynasty in the temple.In order to understand the materials and techniques used for the sculptures,optical microscopy,X-ray diffraction,micro-infrared spectrometry,micro-Raman spectrometry,scanning electron microscopy-energy dispersive spectrometry and X-radiography were used for scientific analyses.The results show that 1)the sculptures were repainted;2)the internal structure was a cross wooden skeleton;3)the mineral compositions of the soil in the coarse and fine clay layers were basically the same,with the soil featuring high strength,strong weathering resistance and good plasticity;4)the coarse clay-reinforcement materials were wheat straw and wheat husk,and the fine clay-reinforcement materials were cotton and hemp;5)the coloration components of the pigment layer were common mineral pigments seen in ancient murals,except for the blue one.These research results may provide a scientific basis for the follow-up conservation and restoration of the painted clay sculptures at Puzhao Temple,and also scientific information for the study of the traditional techniques for Yuan Dynasty painted clay sculptures in Shaanxi.
